Application filed August 28, 1915, Serial No. 47,777. Renewed February 19, 1917. Serial No. 149,654.

To all whom it may concern:

Be it known that I, NIcHoLAs A. BECKER, a citizen of the United States, residing at South San Francisco, in the county of San Mateo and State of California, have invented certain new and useful Improvements in Curb-Bars, of which the following is a specification.

The present invention relates broadly to protecting structures for corners, edges and the like of cement or other composite work.

The object of my invention is to provide a simple, inexpensive and efficient protector or guard for use in connection with cement work and one particularly designed to be employed in connection with cement or concrete street curbings to protect the exposed corners and face thereof from being chipped or broken by sudden shocks; to provide a structure which when positioned will project a slight distance over the top and side faces of the curb and the corners thereof and thereby protect the same from becoming chipped or broken; to provide one which is thickened or formed with a reinforcement adjacent its corner curved section where the heaviest shocks or greatest wear occurs; and to provide one with means for preventing the overhang of the vehicle tires from contacting with the side face of the curb below the protecting guard, thereby protecting the face of the curb from injury or wear due to the action of the vehicle tires.

With the above mentioned and other objects in view the invention consists in the novel construction and combination of parts hereinafter described and illustrated in the accompanying drawings; it being understood that various changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

To more fully comprehend the invention, reference is directed to the accompanying drawings, wherein- Figure 1 is a view in'section of a curb with an embodiment of my invention applied thereto.

Fig. 2 is a transverse sectional view of a slightly modified form of device.

Referring more particularly to the drawings, the numeral 1 is used to indicate a suitable curbing formed preferably of concrete or cement and having the top and side faces 2 and 8.

In Fig. 1 of the drawings, the improved guard is illustrated as embedded in the curbing at the corner thereof, with its outer surface adjacent its side edges flush with the outer surface of the curb and the guard or protecting structure is shaped by any suitable process and from any suitable material, and said guard comprises a body member 4 shaped as a straight section for protecting the front wall surface of the curb and adapted when positioned to extend downwardly from the corner edge of the said curb over a portion of the vertical side wall 3 thereof, said member 4 is provided with an upwardly and inwardly curved head or member 5 which is adapted to extend over the corner of the curb and the same when positioned extends a slight distance inwardly on the upper horizontal surface 2 of the said curb.

An outwardly projected or thickened portion 6 of the head 5 extends longitudinally of the guard, and the same is positioned intermediate the edges thereof and preferably at the curvature of the member 5 relative to the member 4 so as to resist the heavy shocks or blows which would normally strike the corner of the curb. The outwardly projecting or thickened portion 6 overhangs the outer face of the straight side wall or member 4 and prevents the overhanging or projecting edges of the vehicle tire from contacting with the vertical side wall surface of the curb below the guard positioned within the curbing.

The guard or protecting structure is anchored in position by the anchoring bar 7 which extends substantially horizontally into the curb and projects inwardly from the inner surface of the straight side wall or member 4 at right angles thereto. The said anchor bar is provided at its outer end with an enlarged head 8 and is passed through a suitable opening 9 formed in the straight side wall or member 4 of the curb guard and the anchor bar is curved at its inner end, as at 10, and the curvature thereof prevents the withdrawal of the same from its embedded position after the concrete or cement forming the curb hardens or sets.

By the employment of my improved guard, the corner of the curb and the side and top faces thereof adjacent the corners extended or'thickened portion 6 projected, beyond the facev of they head member of is protected from injury, andthe outwardly the guard reinforces the same at the point where the same is subjected to the greatest shocks and strains, and the same prevents the injury of thecurb below the guard by the overhang of the vehicle tires. It is ap parent that by projecting the anchor bar 7 inwardly at substantially right angles to the "vertical"portion of the protecting guard member 4, and extending the same substanti'ally horizontally into the curb, that all shocks 0r strains re'ceivedby the guard or protectingstructure are not transmitted longitudinally of the anchor, and which when so transmitted tend'to split the cement forming the curb, as is the case with the present form of anchor means for the curb guards,

thereof in no manner injures the composite curb. 7 7

In the modified form of device disclosed in Fig: 2 of the drawings, the anchor bar is threaded into the body member 4 as at 11,

and the inner face of the said body member 4 and thehead member 5- of the protecting guard structure is grooved longitudinally as at 12 to provide channels to receive the con- Gopies of this patent may be obtained for Having thus described my invention, what I claim is A rolled metallic protecting guard for composite structures comprising a straight wall or body member for protecting the front wall surface of the structure, an enlarged upwardly projected inwardly curved head member formed integral with the body member for overlying thecorner edge and top wall surface of the composite structure, said head member being of great'erthickness than the body member and said increased thickness providing an overhanging section projected outwardly beyond the face of the front wall or body member of the guard, and an anchor detachably secured to and extended transversely through the body member of the-guard for positioningwithin the structure to be protected and to lie in a plane parallel with the top wall surface thereof.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
